ZHENSHUI Portable Thermos Slim Flask STAINLESS STEEL 500ML

Description:

This is a set of four slim, modern vacuum-insulated bottles designed for portability and style. They come in a versatile, matte color palette featuring military green, crisp white, slate gray, and classic black. The bottles have a minimalist, cylindrical shape and are branded with the word "ZHENSHUI" near the base. A metallic silver ring accents the top, adding a sophisticated touch to the screw-on lid. These are ideal for keeping drinks at the desired temperature whether you're commuting, at the office, or enjoying the outdoors.

Feature: 

The defining feature of these bottles is their vacuum insulation, which provides excellent temperature retention. This means they are engineered to keep beverages hot for several hours (like coffee or tea) or cold for an extended period (like water or iced drinks). The double-walled design with a vacuum seal minimizes heat transfer through conduction, convection, or radiation, ensuring your drink stays the way you want it for longer.

Material: Stainless Steel

These types of high-performance insulated bottles are almost always constructed from food-grade stainless steel (most commonly 304 or 18/8 stainless steel).

Stainless steel is chosen for several reasons:

Durability: It resists rust, corrosion, and impacts, making the bottle long-lasting.

Safety: It doesn't leach harmful chemicals into beverages and is BPA-free.

Purity: It doesn't retain flavors or odors from previous drinks, keeping your water tasting fresh.
